Hilbert‘s Sixteenth Problem and Its Generalization

This paper deals with Hilbert‘s 16th problem and its generalizations.The configurations of all closed branches of an algebraic curve of degreee n are discussed.The maximum number of sheets for an algebraic equation of degree n and the maximum number of limit cycles for a planar algebraic autonomous system are achieved.The author also considers different generalizations and some related problems.     

Two ancient rounds of polyploidy in rice genome

An ancient genome duplication (PPP1) that predates divergence ofthe cereals has recently been recognized. We report here another potentially older large-scale duplication (PPP2) event that predates monocot-dicot divergence in the genome of rice(Oryza saliva L.), as inferred from the age distribution of pairs of duplicate genes based on recent genome data for rice. Our results suggest that paleopolyploidy was widespread and played an important role in the evolution of rice.     

Investigation of heat sink of endothermic hydrocarbon fuels

Endothermic hydrocarbon fuels are advanced coolants for high-temperature structures of spacecraft. No data of tested-cooling-ability of endothermic fuels have been broadly discussed in literature. In this work a high-temperature flow calorimeter was designed, and the cooling capacity of six different hydrocarbon fuels were measured. Experimental results showed that these hydrocarbon fuels have capacity for cooling high-temperature structures, and that the cooling capacity of fuel N-l can reach 3.15 MJ/kg, which can nearly satisfy the requirement of thermal management for a Mach 3 cruise aircraft, whose heat sink requirement is about 3.5 MJ/kg. The endothermic velocity of hydrocarbon fuels was also measured by the calorimeter.     

师生冲突的概念界定与分类探究——基于刘易斯·科塞的冲突分类理论

论文通过借鉴和辨析社会学理论中的冲突概念,对师生冲突概念作出界定。根据美国当代社会学家刘易斯·科塞的冲突分类理论,对学校师生冲突进行分类研究。在此基础上提出了三个观点:学校师生冲突的多数属于非现实性冲突;师生结构由紧密走向松散是师生冲突增多的重要原因;师生冲突具有一定的正面功能。     

浅谈提高森林公安队伍素质的途径

目前,森林公安队伍有半数以上民警未受过高等教育,随着我国生态文明建设进程的不断推进,将难以适应森林公安工作任务的需要。提高森林公安队伍素质,要加强森林公安民警的学历教育,加强业务技能培训,促使民警不断学习新知识、新技术,适应形势发展需要,跟上时代的步伐。

深刻把握“三个代表”重要思想的哲学基础

江泽民同志提出并系统阐述的“三个代表”重要思想，是我们党的立党之本，治国之基，力量之源，是当代中国马克思主义理论发展的最新成果。本探讨了“三个代表”重要思想形成的新的实践基础，分析了这一重要思想是在我们党和国家所面临的伟大历史转折时期，在复杂多变的国际形势的特定历史背景下形成的。章还探讨了“三个代表”重要思想立论的哲学基础。
